'Righteous' in the Bible

The Lord will return his bloody deeds upon his own head, because he struck down two men more righteous and honorable than he and killed them with the sword, without my father David knowing: Abner the son of Ner, commander of the army of Israel, and Amasa the son of Jether, commander of the army of Judah.

then hear from heaven and act and judge Your servants, condemning the wicked by bringing his guilt on his own head, and justifying the righteous by rewarding him in accordance with his righteousness.
